22 Claims.

This invention relates to printing machines and mechanisms for use therein and therewith such as computing, accumulating. paging and proofing, number and numerical accounting data, printing, sub-totaling, and kindred mechanisms, and the primary object is to'expedite preparation of business instruments and the like and records thereof and in this connection it is to be-understood that the term business instruments is used hereinafter in the generic sense with reference to a wide variety of sheets of which specific examples are checks drawn on banks, public utility bills, insurance notices, invoices and the like.

This application is a continuation in part of my application Serial No. 221,841, filed July 28, 1938, now issued as United States Letters igtzent No. 2,296,277, patented September 22,

Exemplifications of printing machines of the kind to which this invention generally pertains are to be found in, for example, United States Letters Patent 2,041,183, 2,083,061, 2,132,411 and 2,132,413. Usually a roll of paper is mounted in proper relation with machines of this kind and a web is withdrawn therefrom and led to the machine. Sheets cut from this web, or which are removed from a stack of pre-cut sheets stored in the machine, are fed through the machine past one or more printing positions whereat impressions are made thereon either directly from printing, printing and control, or like devices that are sequentially fed through the machine or from suitable printing mechanisms set up under control of printing and control or like devices or record cards or the like. Further-.

more, in machines of this kind constantly reoccurring data are printed on the sheets before pre-cut sheets are stacked in the machine or before the sheets are severed from a web or after such severance and sometimes such impressions are made on the sheets both prior to and after severance thereof from a web.

The data printed on sheets or business instruments such as those to which reference has been made, other than the constantly reoccurring data, may be conveniently classified as changeable data and variable data. The changeable data are usually those which are directly printed from printing, printing and control, or like devices and usually consist of an identification, such as a name and address, and the variable data are usually numerical accounting data, such as the amount of money to be paid pursuant to a check drawn 'on a bank these has been the use of printing devices, from which the changeable data were printed directly, and record cards, usually perforated record cards, under control of which the vari-- able data were printed. In such usages, an example of which will be found in United States Letters Patentv 2,083,061, the printing devices and the record cards are sequentially fed through a suitable printing machine wherein the changeable data are printed by making one or more impressions from each printing device on each business instrument and the variable data are printed by making one or more other impressions on each instrument under control of each record card. It is of course essential that the changeable data printed on each instrument from the printing device be related to the data printed under control of the record card, and vice versa, and to this end the printing devices and record cards have been manually compared before being passed through the machine so as to insure that the devices and cards were arranged in corresponding sequences to thereby insure that the changeable and variable data appearing on each instrument relate to the same person or account or the like.

As a further means of assuring that the changeable and variable data printed on each instrument in such usages will be related to each other,.that is, will relate to the same person, account or the like, it has been proposed to equip the machines through which such devices and cards are fed with'means for comparing each device and card, from which and under control of which impressions are to be made on a particular business instrument, with each other, and this means is usually operated to interrupt operation of the machine or to afford other-indication when a particular printing device and a particular record card relating to a particular business instrument did not correspond. Inasmuch as, in such usages, the sequencing of the printing devices and the record cards was performed manually, the human factor entered into the operations which, of course, gave rise to error, and where the means in the machine 'operated to interrupt operation of the machine when a particular card and device did not correspond the productive capacity of the machine was impaired for, ob-

viously, time was lost each time machine operation was interrupted. Furthermore, it is a time consuming task to determine the reason for machine stoppagein such instances and to locate the related printing device and record card which further operated to reduce the productive capacity of the machine.

In view of the foregoing it has also been proposed to provide printing and control devices, an example of which is disclosed in Patent No. 2,132,412. Such printing and control devices include, for example, embossed type characters from .which impressions can be made directly and also include a perforated or other area affording control means under control of which the variable data can be printed. The use of such devices eliminates the necessity of comparing printing devices and record cards or the like in order to insure that related changeable and variable data will be printed on the same instrument. However, in those instances heretofore where it has been proposed to employ printing and control devices for producing changeable and variable data on business instruments, the control means provided on the devices were direct representations of the variable data that were to be printed under controlthereof. In view of this it' was necessary to change the control areas of the printing and control devices each time there was a variation in the.var iable data. This was required not because of any limitation in the printing and control devices but rather by reason of limitations in the machines in which the printing and control devices were employed, which is to say, such machines heretofore have not been equipped to interpolate the data represented in the control areas of the printing and control devices or, more specifically, such machines have not been equipped to perform computing operations based upon the data represented in the control areas of the printing and control devices.

In view of the foregoing, it has further been proposed to enable data represented in the control areas of printing and control or like devices to be interpolated in the machine through which such devices are passed and more specifically to enable computing operations to be effected in a machine under control of the control areas on printing and control or like devices passed through the machine as more fully disclosed in my co-pending application Serial No. 221,841, now issued as United States Letters Patent No. 2,296,277, patented September 22, 1942.

A specific example of the use of printing and control devices in the preparation of business instruments is the preparation of so-called dividend checks of a corporation by means of which dividends declared by the corporation are distributed to its shareholders. Heretofore where printing and control devices have been employed in the preparation of dividend checks, each printing and control device related to a particular shareholder whose name and address (changeable data) was directly printed from type characters or the like on a printing and control device relating to the particular shareholder and the control area of such device was arranged to bear representations of the amount of dividend to be paid to the particular shareholder. Now it will be recognized that in a long list of shareholders the changes in holdings of the individual shareholders between payments of successive dividends will not be likely to entail nearly as many will occur when the dividend rate of the corporation varies, for when the dividend rate varies it is necessary to change each and every printing and control device if the amount of dividend payabl to the respective shareholders is directly represented in the control areas of the devices pertaining to such respective shareholders. It will be apparent from this that a marked advantage will accrue from representing the holdings of a shareholder in a corporation on the printing and control device pertaining to the shareholder rather than directly representing thereon the amount of dividend payable to the shareholder as has been done heretofore.

It is to be understood, when reference is made herein to the preparation of dividend checks of a corporation, that this is merely an exemplary utilization of my invention but one which is common and convenient in describing the various aspectsof my invention. However, my invention, as stated heretofore, is capable of use in a wide variety of instances in which sheets are to be printed and among other instances may be cited the preparation of tax bills, public utility bills, insurance premium notices','chain store billings and allied and kindred operations. Therefore, while reference is made hereinafter to the preparation of dividend checks of a corporation, it is to be understood that this is merely exemplary and is not, therefore, to be taken as a limitation of my invention.

Perhaps the most frequent interpolation of data such as may be represented in the control areas of printing and control or like devices is a computing operation entailing multiplication, one factor of each'such multiplications for example, being represented in the control area of a printing and control or like device, and the other factor may also be derived therefrom or elsewhere as more fully'disclosed in my aforesaid co-pending application Serial No. 221,841. In the preparation of dividend checks of a corporation thefactor represented in the control area of a printing and control device to be utilized in such preparation will be the number of shares of stock owned by the shareholder to Whom th particular printing and control device relates, and the other factor, the dividend rate, may be included or set up in the machine. In an instance where the dividend rate will remain constant for a large number of operations, multiplications, in such an instance, this factor of the various multiplications may advantageously be, in effect, constantly represented in the machine. The means and method of effecting the multiplications in the present machine, which are of the aforesaid nature, are more fully-discussed and disclosed in my aforesaid co-pending application Serial No. 221,841, to which reference is made hereinabove.

In machines wherein business instruments and the like are prepared it is often advantageous to prepare what is known as a proof sheet and in other instances it is desirable to not only produce proof sheets but to also accumulate totals and the like and sometimes only totals are accumulated. proposed heretofore for enabling this to be accomplished and usually in such prior arrangements it has been customary to directly set up whatever means are to be operated for accomplishing the foregoing directly from set-up mechanisms in the machine. This, however, some times entailed complicated interconnections and Various arrangements have been of the present invention.

of the machine and the manner in which such operations could be performed and particularly the positions whereat such operations could be performed.

In view of the foregoing, an important ob-.

ject of this invention is to enable the preparation of proof sheets, the accumulation of totals, the production of ancillary or related impressions on sheets, and many of the so-called auxiliary operations to be performed at wide variations of positions in the machine without the necessity of providin physical connection between the mechanisms performing such auxiliary operations and themeans by which the mechanisms are set up or controlled.

It is contemplated by my invention that the means which are operated under control of the control areas on printing and control or like devices which, in the present instance, is the multiplying means, will be equipped to not only in some instances accumulate totals and in most instances to display the results of the operations thereof as either by setting up a register or as is done in the present instance by the setting up of type characters, but that an additional record will be produced as by perforating or otherwise providing control means in cards or the hire and so to do constitutes another important object Other objects related to the foregoing are to produce a perforated record card or the like in the course of operation of the machine and to incorporate into' such perforated record card perforations or the like representative of the result of an operation of the machine such as, for example, the value of a final product ascertained in the multiplying means; to feed such perforated record cards or the like through the machine in such a way as to enable such cards to be utilized in the performance of operations on the sheet or the like receiving impressions or having other operations performed thereon from the means in which the perforated record cards or the like are produced; to utilize such perforated record cards or the like to set up means for perforating what may well be called auxiliary operations in the machine; to enable one or more of such means for performing auxiliary operations to be located at desired or advantageous positions in the machine and to feed the perforated record cards or the like to such positions whereby physical connection of such means'for performing auxiliary operations with the means under control of which such operations are to be performed may be avoided; to employ an accumulator in the machine in which totals or the like may be entered or accumulated under control of perforated record cards orthe like produced as an ancillary operation to some other operation in the machine; to employ printing means settable under control of such perforated record cards or the like to produce printed records either on sheets passing through the machine and receiving other impressions or having other operations performed thereon or onto special sheets or webs passed through the machine for the purpose of producing proof sheets and the like; and to enable perforated record cards or the like produced ancillary to some other operation in the machine to be collected for use in controlling other operations in the same or a related machine.

'- In those instances where what has been called a proof sheet has been prepared, it has usually been customary to produce the impressions on a web and in some instances this web, after the impressions were made thereon, has been wound into a roll but in other instancespredetermined lengths of such a printed web have been fed past a severing means operable to divide the web into sheets or pages of substantially uniform size which were then collected and used as required or desired as,for example, by being bound in loose-leaf binders for checking and reference purposes and the like. Arrangements of this kind are commonly known in the art to which this invention pertains as pagers and proofers, and still another important object of this in vention is to provide a novel pager and proofer and particularly one especially adapted for use with the machine of the present invention.

Other objects related to the foregoing are to support a roll from which a web may be withdrawn for passage through the novel pager and proofer of this invention in such a way that the normal operation of the machine with which the pager and proofer is used is not impaired; to avoid the necessity of changing the construction of the machine particularly in so far as the platen or other impression making means are concerned in order to accommodate webs of different widths and enable impressions to be made on the web; to feed the web through a platen or other movable impression making member to enable the web to move therewith without relievvals into sheets of a,predetermined size and on the whole to provide a simple and economical pager and proofer of efficient and positive operation.

A further important object of this invention is to take what is referred to in the art as subtotals whenever desired by the operator or automatically at the foot of each proof sheet which sub-totals are the totals of all amounts printed on the proof sheets prior to the taking of the previous sub-total.

Many other objects and advantages of the present invention will be apparent from the following description in which reference is made to the accompanying drawings wherein Fig. 1 is a perspective view of bodying my invention;

For a detailed description of that part of the illustrated machine which is not specifically described in this application reference may be made to my aforesaid co-pending application Serial No. 221,841. It may be observed however that in the printing machine shown in Figs. 1 and 5 is so arranged that a roll of paper R may be suitably supported at one end of the machine, and a web W is withdrawn from the roll R and passed into a signature printing and web severing unit 89. The free end of the web W is led past severing means in the unit 89 which is operative at certain times in the course of operation of the machine to sever sheets as S, Fig; 3, from the web W. The sheets thus severed from the web W are deposited in a sheet guideway G provided longitudinally alon the table top of the machine. The sheets S are fed along the guideway G so as to come to rest in a first printing position associated with the multiplying mechanism M and at this position variable numerical data or amounts are printed on the sheet. Such numerical amounts are determined by the multiplying mechanism M under control of means embodied in printing and control devices D, Fig. 2, which are passed through the machine, the details of the structure and function involved in this operation being described in detail in the aforesaid parent application Serial No. 221,841. The sheet is then advanced to a second printing position beneath an impression means such as a platen P, and the platen is operated to produce an impression on the sheet S from printing means embodied in the same printing device from which the variable numerical data printed on the sheet was derived.

The printing devices D are withdrawn one by one from the bottom of a, magazine H mounted on the rear ends of a pair of guide rails 254, and the printing devices are advanced forwardly in 'a step by step manner along a guideway formed in part by the rails 254. In such advancing movements the printing devices D come to rest on an anvil 264 so that impressions may be made therefrom by the platen P. The advancing movements are imparted to the printing devices D by single cycle advancing mean 300 controlled from a main coordinated control means such as the main control cam shaft of the machine by means including a control cam shaft of the machin by means including a control solenoid 3H1, as described in detail in the parent application Serial No. 221.84 After the desired impression or impressions have been made from a printing device D, the advancing means discharges the printing device forwardly and it is deposited in a collecting means such as one of the drawers J.

After an impression has been made by the platen P on a sheet S from a printing device D, the sheet S is further advanced along the sheet guideway G and is passed through a form printing unit U so that reoccurring lines or text matter may be printed thereon. The completed checks or sheets S are discharged from the form printing unit U into a suitable-sheet collector K.

In instances where, for example, as in the present instance, checks are being printed and in many other operations, it is desirable to preserve a record of what has been printed on sheets as S and to this end what is known as a proof sheet is prepared. Such proof sheet is usually prepared in the form of a web and this web is subsequently divided at predetermined intervals to afford sheets or pages of uniform size that may be conveniently bound as in loose leaf binders or the like to thereby aiford a permanent record of what is printed in the course of a run of the machine. Mechanisms which so print on webs and which divide the webs into pages affording proof sheets have come to be known as pagers and proofers and such mechanism is embodied in the machine disclosed herein.

The pager and proofer in the present instance is generally indicated by 900 and operates to produce a proof sheet such as is fragmentally illustrated in Fig. 4 and which is indicated by this proof sheet passing through the machine in the form of a web 9lll-W. The proof sheets 9M desirably include data A printed from the printing means of the printing devices D, as well as a number N' and numerical data V all of which are arranged in lines across the proof sheet or web in such a manner that the'data A, N and V in each line constitute duplicates of data printed on a particular check or sheet S.

In the machine as herein shown the data, A, N and V are printed on the proof sheet or web SUI-W at the same printing station at which the data A are printed upon the checks or sheets S, the proof printing operations being accomplished in alternate machine cycles during which a sheet S is not present beneath the platen P. In the accomplishment of this proof printing operation the machine herein shown utilizes an auxiliary printing mechanism VP, Fig. 5, disposed in operative relation beneath the platen P and arranged to be variably set up under the control of the multiplier M to print numerical amounts corresponding with amounts previously printed by the multiplier. Thus, as explained in detail in the parent application, the machine has punching mechanism PM operatively associated with the multiplying mechanism M so as to produce individual punched cards having perforations therein corresponding with the numerical amounts ascertained and printed by the multiplier. These cards are advanced along a card guideway CG, to a sensing station associated with the auxiliary printing mechanism VP where the numerical amounts represented on the cards are sensed and set up in the auxiliary printing mech anism VP. Thus when the platen is operated to print the data A on the proof sheet or web. the

platen will act as a back up member to enable hammer mechanism in the auxiliary printerVP to print the set up numerical amount on the proof sheet in the appropriate line thereof.

In the present instance the web 901--W, Fig. 5, is withdrawn from a roll Sill-R which is rotatably mounted in a stand 902. This stand comprises spaced upright brackets which have bifurcations as 903 in the upper edges thereof and pairs of rollers adjacent the bottoms of these bifurcations so that a shaft 905 on may rest on these rollers to thereby afford a frictionless support for the roll, and in this way inertia incident to the withdrawal of the web 901W' from the roll is substantially reduced.

In the present instance the web 901--W is withdrawn from the roll 901--R and passed about a roller 906 in the stand 902 and from this roller the web is led across the bottom of the machine to a roller 901 carried by brackets as 908 which are secured to uprights as From the roller 901 the web passes to a roller 909 mounted between side plates 910 and 911, Fig. 14, which depend from the side plates 912 and 913 of the pager and proofer unit, the roller 909 being part of a web looper.

A roller 911 is the movable part of the looper for the ,web 901-W and to this end vertical slots as 914 and 915, Figs. and 10, are provided in, the side plates 910 and 911 and the ends of a shaft 916 are disposed in these slots, the roller 911 being carried by the shaft 916. Another shaft 918 is journaled in the side plates 9 I 0 and 91 1 and carries a roller 919 that is also part of the looper for the web 910-W. The roller 909 has friction means such as rubber bands provided on the periphery thereof to insure good frictional engagement thereof with the web '901-W. As shown best in Figs. 8, 12 and 14, a worm wheel 920 is fast on the shaft carrying the roller 909 and a worm gear ,921 on the shaft of a motor 922 meshes therewith, this motor being set in operation when the loop, drawn in the web 901-W by the roller 911 between the rollers 909 and 919, is reduced in size.

Hence, means responsive to the size of this loop are provided and to this end one end of the shaft 916 is engageable with a cam surface on an arm 923 which is pivotally mounted as indicated at 924 on the side plate 9| 1. The arm 923 carries a pin 925 of insulating material that is engageable with a switch blade 926 that carries a contact which is engageable with the contact on the switch blade 921. As the web passes over the roller 919 in such a way as to reduce the size of the loop drawn in the web by the roller 911, the shaft 916 moves up into a position substantially like that shown in Fig. 13, whereupon this shaft acts on the cam surface on the arm 923 and through the pin 925 this engages the contacts .on the blades 926 and 921 to thereby close the circuit to the motor 922 which thereupon rotates the shaft carrying the roller 909 to withdraw the web 901-W from the roll 901-R. Thereupon the loop in theweb increases in size and as the size of the loop between the rollers 909 and 919 is increased to th e size desired the roller 911 moves downwardly and the shaft 916 so moves along the cam surface, on the arm 923 that the contact on the blade 926 isseparated from the contact 921 to open the circuit to the motor 922 whereupon further withdrawal of the web from the roll 901-3 is interrupted when the loop'attains the desired size. 1

as 904 are mounted on the stand 258 of the frame.

which the roll 901-R is supported between rearwardly projecting extensions on the plate 649 so that the web passes up over what may be called the rear face of the platen P, and from the roller 931 the web 901--W is passed between the plates 639 and 586 of the platen P.

From the space between the plates 639 and 566 the web passes to a roller 932 rotatable on a shaft 933, the ends of which are mounted in arms 934 and 935, Figs. 8 and 10, which depend from the bearings 936 and 931 on the side plates 912 and 913 and in which bearings the shaft 938 is journaled. The ends of the shaft 933 extend through arcuate slots as 939 in the side plates 912 and 913 and by means of bolts as 940 passed into the ends of the shaft as 933, the roller 932 may be maintained in adjusted positions. The adjustment afforded for the roller'932 enables adjustment in a loop defined in the web intermediatethe roller 931 and a roller 941 on the shaft 938. An adjustment of the size of this loop varies the location of matter printed on the web 901-W and the position at which severing means, described hereinafter, is operative to divide the web into pages'so as to thereby regulate thesize of the pages and insure severing of the pages intermediate impressions made thereon rather than through such impressions.

The side plates 912 and 913 are tied together by cross members as 942 so that a unitary construction is provided to enable the pager and proofer to be handled as a unit. Inasmuch as the web 901--W may vary in width in different runs, the side plates 910 and 91 l, which have been described as depending from the side plates 912 and 913, are adjustably mounted on a cross bar 943 by the use of clamping screws as 944, this arrangement enabling the plates 910 and 911 to be spaced from each other sufficiently to neatly accommodate different widths of web therebetween. It will also be understood that the rollers 909', 911 and 919 may be discontinuous to additionally furnish accommodations for webs of different widths.

The amonut of travel of the platen is relatively restricted and the passes of the web 901-W to and from the platen are in substantially straight lines and hence in the reciprocatory movement of the platen P described hereinabove the length of these passes of the web is not changed to such. a degree that the web becomes slack, this also being augmented by the tension applied on the web by the roller. 911, it being understood that the shaft 9 1 6 is at no time enabled to seat in the bottom of slots as 915 in the course of operation of the motor 922 to increase the size of the loop in the web.

Inasmuch as impressions are made on the web 901--W at spaced intervals and as, in the present instance, such impressions are made in alternate imparted to the web 96!-W and in the present instance such movement is imparted to the web as it passes about the roller 94!. As can be seen in Figs. 7 and 10, a clamping roller 945 is fast on ashaft 946 which is journaled in bearing blocks 941 and 948 which, as shown best in Fig. '7, have slots as 949 in opposite edges thereof, the portions of the bearing blocks intermediate these slots being fitted into bifurcations as 956 in the upper edges of the side plates 9!2 and 9!3 to thereby afford a slidable mounting for the hearing blocks 941 and 948, the shaft 946 and the clamping roller 945. In order to maintain the clamping roller 945 in web clamping cooperation with the roller 94!, cross bars or strips as 95! are secured to the bearing blocks as 948, Figs. 10 and 16, and springs as 952 extend between these strips and spring anchors on the adjacent side plate, these springs being effective to urge the periphery of the clamping roller 945 into web clamping cooperation with the roller 94!. A web ad.- vancing step by step movement is imparted to the shaft 938 and the roller 94! in a manner described hereinafter.

The web 96!W passes from the roller 932 and about the roller 94! through the bite between this roller and the clamping roller 945 and thence over a ledge 953, Fig. 10, that is fast to a cross bar 954 which extends between the side plates 9 2 and 9| 3. A stationary cutting member 955 is fast on the upper edge of the crossbar 954 and a movable knife 956 is adapted for cooperation therewith, this movable knife 956 being a thin strip of metal and being fast to the concave face of the carrier bar 951, the cutting edge of the movable knife 956 being tapered inwardly and upwardly from the ends thereof,'and this in cooperation with the longitudinal arc imparted to the knife 956 by connection thereof to the above described concave face insures a shearing action in the course of cooperation of the knife 956 with the cutting edge of the stationary cutting member 955 during downward movement of the knife that is effected in the manner now to be described.

The carrier bar 951 is acted on by a spring 951 to hold the knife 956 in engagement with the member 955 and this bar extends between and is carried by arms 958 and 959, Figs. 7 and 10 which, at their lower ends, arev pivotally connected to arms 966 and 96! that are pivotally mounted on studs 962 fixed in the side plates 9!2 and 9 3, the pivotal interconnection between arms as 958 and 96! being shown at 963, Fig. 10. The arms 966 and 96! are in the form of bell cranks having depending arms 964 and 964' which are rigidly joined together for rocking movement in unison by a cross arm 964a. The arm 964 has a roller 965 at the free end thereof and this roller is urged into engagement with the periphery of a cam 966 by springs as 961 that extend between the arms 966 and 96! and spring anchors on the adjacent side plates 9!2 and 9!3. Lugs as 96!! extend inwardly from the side plates 9!2 and 9I3 and have adjusting screws 96! mounted therein, the lower ends of these adjusting screws engaging the arms 966 and 96! and limiting the upward movement thereof induced by the springs as 961.

The cam 966 is rotatably mounted on the shaft 968 that is journaled in the side plates 9!2 and 9!3 and includes a hub 914, Fig. 7. Clutch teeth 969 are provided at the free end of this hub and are adapted for cooperation with clutch teeth 916 provided on the adjacent end of a collar 91! that is fast on the shaft 968. These clutch teeth 969 and 916 and the parts controlling engagement thereof are substantially similar to those described in my co-pending application Serial No. 239,561, filed November 8, 1938, now Patent No. 2,265,133, patented December 9, 1941. l

A plate 912, Fig. 7, rotatably mounted on the shaft 968 is suitably connected, as by pins, to the cam 966. Springs as 913 extend between this plate and the cam 966 whereby the plate is urged into engagement with the inner face of the side plate 9!2 and the cam is urged along the shaft 968 to tend to engage the clutch teeth v969 on the hub 914 thereof with the clutch teeth 916 on the collar 91!. However, engagement of a pin 915 on the hub 914 with a cam surface 916 on the am 911 normally holds the clutch disengaged. The arm 911 is pivotally mounted, as indicated at 918, on the side plate 9l2, a spring 919 being active on this arm to maintain the marginal portion adjacent the free end thereof in engagement with the periphery of the hub- 914.

A plate 986 is pivotally mounted at 98! on one arm of a bell crank 982 that is pivotally mounted on a stud 983 carried by the side plate 9!2. The plate 986 includes a lug 984 that is engageable with the under side of the free end of the arm 911, said plate 986 being urged toward the periphery of the hub 914 by a spring 985. The arm 986 of the bell crank of which the arm 982 is a part is loosely and pivotally connected to the core 981 of a solenoid 988. An arm 989 extends from the bell crank including the arm 982 and a spring 996 is connected to this arm and to a spring anchor on a lu-g 99! carried by the side plate 9!2, this spring being effective to hold the parts in the position in which they are shown in Fig. 10.

When the solenoid 988 is energized the arm 982 is pivoted upwardly as is the plate 986 and the lug 984 thereon and this pivots the arm 911 upwardly to disengage the cam surface 916 thereon from the pin 915, whereupon the springs 913 cause the clutch teeth 969 to engage the clutch teeth 916 and thereupon the cam 966 starts to rotate with shaft 968. Shortly after the cam 966 starts to rotate, the pin 915 engages the plate 986 to disengage the lug 984 from the end of the arm 91! whereupon the spring 919 returns the arm 911 into engagement with the hub 914 so that near the end of a revolution of the cam 966 with the shaft 968 the pin 915 rides over the cam surface 916 to separate the clutch teeth 969 from the clutch teeth 916, and when the pin 915 comes to rest in engagement with the abutment 992 on the arm 911 the cam stops in its at rest position shown in Fig. 10'.

The solenoid 988 is energized each time the movable knife 956 is to move into cooperating relation with the cutting edge on the stationary cutting member 955, this being effected after a predetermined number of impressions have been made on the web 96!-W and a predetermined length of the web, which is to constitute a page, as hereinabove described, has been fed past the knife 956, pages severed from the web 96 !W by the knife 956 passing into the receiver 993, Figs. 5 and 10.

The shaft 968, Figs. '7, 10, 12, 14, is rotated each time the printing and control devices D are advanced by the carrier bar as 252 and to this end the following arrangement is provided: A gear 994 is rotatably mounted on the shaft 968 and has clutch teeth 995 at the freeend of a hub thereon. these clutch teeth being adapted for cooperation with'elutch teeth 996 provided on a sleeve slidably but non-rotatably mounted on the shaft 968. The clutch teeth 996 on this sleeve 991 are urged toward the clutch teeth 995 by springs 998 extended between the other end of this sleeve 991 and a collar 999 fast on the shaft 968, and itwill be recognized that this arrangement is part of a clutch structure such as that disclosed in .my aforesaid co-pending application, Serial- No. 239,561, flied November 8, 1938, now Patent No. 2,265,133, patented December 9, 1941. A pin I000 is fast in the sleeve 991 and is engageable with a cam surface on a plate IOI that ispivotally mounted as indicated at I002 on the outer face of the side plate 9 I3, this plate being urged into engagement with the periphery of the sleeve 991 by a spring I003. In the manner above described an arm I004 is connected to the core I005 of the solenoid I006 is effective to retract the arm IO0I from engagement with the pin I000 whereupon the springs 998 engage the clutch teeth 996 with 'the clutch teeth 995 to thereby connect the gear 994 to the shaft 968 and thereupon the shaft 968 is caused to make a complete revolution, the pin I000 engaging a cam surface on the plate IO0I to disengage the clutch teeth 998 from the clutch teeth 995 at the end of this single revolution. Rotary movement is imparted to the gear 994 from the pinion I001 mounted on a stub shaft I008 carried by the side plate 9I3. A pulley I009 is unitary with the pinion I001 and a belt IMO is passed about the pulley I009 and about a pulley IOII fast on the shaft of the motor IOI2 carried by a bracket IOI3 that is supported from the side plates 9 I 2 and M3. When the machine and pager and proofer are in operation the motor IOI2 is constantly rotating. It is to be understood that if desired the motor IOI2 and the pulley IOII on the shaft thereof could be supplanted by a suitable pulley on .the main drive shaft I9 of the machine. The use of amotor as I0 I2 is preferred where the pager and proofer, as in the present instance, is an attachment rather than a unitary fixed part of the machine.

It will be understood that the above referred to step by step advancing of the web 90 I--W is to be imparted to the web each time the'shaft 968.is caused to rotate and to this end a ratchet IBM is fast on the shaft'938 and the teeth in this ratchet are spaced apart in the amount that the web 90'I--W is to be advanced intermediate each impression operation thereon, a ratchet with differently and properly spaced teeth being substituted for the ratchet IOI4 when a different spacing between impressions on the web is desired. A pawl I0 I 5 pivotally mounted on a rocker [M6 is urged toward the teeth of the ratchet as W by a spring IOI1, the rocker IOI6 being pivotally mounted on the shaft 938. One end of a link I0! is connected to the rocker IOI6 and the other end of this link is adjustably connected, as indicated at IOI9, to a crank arm I020 fast on the shaft 968. Each time the shaft 968 rotates a reciprocatory movement is imparted through the link IOI8 and in the first part of this reciprocatory movement the pawl IOI5, which at this time will be positioned to engage a tooth in the ratchet IOI4, causes the ratchet and therefore the shaft 938 and the roller 9 thereon to make an advancing movement. In the other portion of this reciprocatory movement, which is in the oppositedirection, the pawl IIII6 is retracted from engagement with a given tooth on the ratchet IOI4 back into position to engage the succeeding tooth, the parts coming to rest at the time the pawl IOI6 attains position to engage this succeeding tooth. l The rotation imparted to the shaft 938 is suflicient to advance the web in the amount desired intermediate impressions made thereon, these impressions being made in the manner described in full detail in the manner described in. my aforesaid co-pending application Serial No. 221,841.

As has been stated heretofore, a number of impressions are made on the web 90I-W and this web. is then divided into pages of predetermined size, and this means that the solenoid 988 is to be energized only at infrequent intervals, that is, only after a predetermined length of web has been fed past the knife 956, or. stated otherwise; only after a predetermined number of impressions have been made on the web. Hence, to effect this and in order to insure that all of the pages will be of uniform size, a timing arrangement is provided which causes the solenoid 988 to be energized at times which will cause the knife 956 to be operated to sever the web 90 I-W after a predetermined length of web and therefore a predetermined number of impressions thereon have been fed past this knife, and this is accomplished in the following manner:

A stub shaft I02I, Figs. '1 and 8, is mounted on the outer face of the side plate 9I2 and a ratchet I022 is rotatably mounted on this stub shaft, a friction spring I023 being effective onthe ratchet to prevent undesired movement thereof. A rocker I024 is also mounted on the stub shaft I02I and one end thereof projects into a position below the shaft 968 so as to be engageable by a pin I025, Fig. 7, on the crank arm I020 in each rotation of this crank arm. A pawl I026, Fig. 8, is mounted on the other end of the rocker I024 and is urged into engagement with the teeth of the ratchet I022 by a spring I021. A spring I028 acts. on the rocker I024 and urges this rocker toward engagement with the hub of the crank arm I020 So that this hub acts as a stop to overcome the effect of the spring I028, the pin I025 of course, when effective on the rocker I024, disengaging it from the hub of the crank arm I020.

Each time the pin I025 engages the rocker I024 the pawl I026 is engaged with one tooth on the, ratchet I022 in the first part of the reciprocatory movement of the rocker I024, to advance the ratchet I022, and then in the latter part of this reciprocatory movement, which is, of course, in

- the opposite direction, the pawl I026 isretracted slightly more than the length of one tooth on the ratchet I022 against the action of the friction spring I023.

A switch, generally indicated by I029, Figs. '1 and 22, is mounted on the side plate 9I2 and includes blades I030 and I03I. A sheet I032 of insulating material is mounted on the top side of the blade I03I' in position to be engaged by a pin I033 extending from the outer face of the ratchet I022. In the course of the advancing -movement of the ratchet I022 in a step by step manner induced as above described, the pin I033 moves into engagement with the sheet I032 of insulating material and thereupon a contact on the blade I03I is engaged with a contact on the blade I030 whereupon the switch I029 is closed. Closure of the switch I029 conditions circuit to the solenoid 988. This circuit also includes a ,timing switch I136, Fig. 22, which inthe present machine is embodied in the auxiliary printing mechanism that prints the data A, N' and V, upon the web I-W. The web feed solenoid I006 and the knife control solenoid 988 are connected in parallel to be operated concurrently upon closure of switch I 136'by a cam I195, whenever the switch I029 is closed. During intervals when the switch I029 is not closed, the cam I195 and associated switch I136 are effective to control only the solenoid I006.

When switch I029 is closed by the ratchet I022 during a predetermined cycle of operation of the pager and proofer unit, it remains closed until the next movement of the ratchet I022 in the succeeding cycle of operation of the pager and proofer. During the interval when the switch I029 is closed, the cam I195 closes the switch I136 and circuit is completed from ground through conductor I139 to terminal I 132 and thence through a conductor I140, winding of solenoid 988, conductor HM, and closed switch I029 to battery, and the knife control solenoid 988 is thus energized. Concurrently therewith, ground is extended from terminal I132 through conductor I133 to the winding of solenoid I006, which solenoid thereupon energizes to effect movement of the web 90IW. During the first half of the feeding cycle which is initiated upon energization of the solenoid I006, the knife 956 remains inoperative due to the configuration of the cam 966, but during the second half of this cycle, at which time the web 90IW has completed its feeding movement and is at rest, the knife 956 is operated by the cam 966 to sever a sheet 90I which is deposited in the page receiver 993. It will be recognized that the ratchet I022 is supplanted by another when the number of impressions caused to appear on each page is to be different from the number appearing on such page when the illustrated ratchet I 022 is used to cause severing of the web 90IW.

As has been stated, the pager and proofer is a unit excepting, of course, the stand 902. When a pager and proofer is to be used, a stand as 902 is rested on the same support as the machine and such stand is connected to an upright as 258 of the frame by an adjustable tie bar as I034 to insure proper alignment of the axle of the paper roll as 90I-R to be mounted therein. The unit including the side plates 9I2 and 9I3 is then mounted in position and this is effected in the manner now to be described.

Posts as I035, Fig. 5, extend upwardly from and are secured to the upright 258 of the frame and a cross bar I036 is extended between the posts as I035 at the upper ends thereof. The bed plate I08 extends across the top edge of the cross bar I 036 and the rear portions of the lower edges of the side plates 9I2 and 9I3 are disposed on the top surface of the bed plate I08 with the rear ends of the side plates in vertical alignment with the cross bar I036. Brackets as I031, Figs. and 8, are secured to the upper portions of the rear ends of the side plates 9I2 and 9I3, as indicated at I038, and these brackets include arms which extend past the side members of the platen structure in outwardly spaced relation with these side members, the rear ends of these arms being pivotally connected, as indicated at I039, to the outer faces of the side plate 254. Hence, the unit comprising the side plates 9I2 and 9I3 is pivotally mounted in position and may be pivoted about the pivotal connections I039 to facilitate servicing or the like.

As is described more fully in my co-pending application, Serial No. 221,841, the variable data V on each proof sheet 90I, Fig. 4, are printed by an auxiliary printing mechanism which is set 4 conductor I153 to the The holding circuit thus established maintains ment of a lobe on-the up under .the control of perforated record cards that are prepared as an incident to the printing of corresponding variable data upon a sheet such as S, Fig. 2. The auxiliary printing mechanism includes an accumulator which functions to receive and accumulate entries of the variable data V that are printed upon the proof sheets 90I. In the present embodiment of the invention, provision has been made for periodically printing upon the web 90I-W, Fig. 10, a subtotal which is the accumulated result of all the entries of variable data V which are printed upon a single one of the proof sheets 90I, so that as each proof sheet is severed from the web 90I-.W it-will bear not only the printed impressions of the variable data V but also the total of such numerical items as have been printed upon the sheet.

For the purpose of operating the accumulator to control the printing of a total by the auxiliary printing mechanism, control of a cam I800 having two lobes thereon is provided as shown in Fig. 8, and this cam I800 is attached to the ratchet I 022. The lobes of the cam I800 are in such angular relation to the ratchet I022 that each lobe contacts an insulating block II on a multi-contact switch generally designated I802 prior to the time when the last numerical item V' is to be printed by the platen P on a portion of the web- I--W which is to be later severed as a proof sheet. Engagecam I800 with the cam surface on the insulating block I80I closes the switches I803 and I804 included in the switch generally designated I802, and this is effective, in a manner explained hereinafter, to to temporarily suspend the normal operation of the machine while a special total taking operation is brought about.

Referring to the wiring diagram, Fig. 22, a starting relay I154 is provided for governing the automatic operation of the machine, as-is described more fully in my aforesaid co-pending application, Serial No. 221,841, where the same reference character is applied to the corresponding starting relay. When the machine is to be initially set into automaticoperation, the cen tral ush button I143 of a switch SS is depressed to close a switch I145 and thereupon battery is extended through a normally closed stop switch I148 and through the switch I145 and conductor I15I to a terminal I152, and from thence through a conductor I 153 to one terminal of the winding of the relay I154, the other terminal of this winding being grounded. The relay I154 thereupon energizes andcloses a contact I 160. Such closure of the contact I establishes a holding circuit for the relay I154, which circuit extends from battery through the normally closed switch I148, conductor I805, normally closed contact I 151 of a relay I158, and conductor I806 to the contact I160 of the relay I 154 and thence through the winding of relay I154.

relay I154 energized so long as both the switch I148 and the relay contact I151 are closed. The relay I154, when energized, causes the machine to operate automatically through the intermediary of means not fully shown in the present disclosure but which are completely described in my aforesaid co-pending application, Serial No, 221,841.

As an incident to such automatic operation of the machine, a cam I085 mounted on a timing cam shaft I018, which is included in the form means in the formprinting unit of the machine, periodically closes a switch I1I6 to thereupon momentarily extend noid 1". It is the solenoid 1" which controls the operation of the auxiliary printing mechanism by operatively connecting the cam shaft thereof to the main drive shaft I8, Fig. 5, of the printing machine when said solenoid is so energized. As has been explained, the timing cam I185, Fig. 22, included in the auxiliary printing mechanism controls the energization of the solenoid I006, Fig. '7, which operates the means for advancing the web 90I-W after each impression has been made thereupon by the platen P.

By referring to Fig. 22, it will be seen that each time the cam surface on the block I80I is engaged by a lobe on the cam I800, the switches I803 and I804 are closed. Cam I800 does not remain in 5, 21 and 22, which solenoid thereupon energizes and retracts its plunger I821. The plunger I821 has a pivoted connection with an arm I828 which is connected to a lever generally designated as 862, which lever, in a manner more fully explained in my co-pending application, Serial No. 221,841, controls the total-taking operation of the auxiliary printing mechanisms. Thus,ener gization of thesolenoid I826 rocks the lever 862 counter-clockwise as viewed in Fig. 21 about its pivot 145 for effecting a total-taking operation,

and as'incident to such movement of lever 862,

a stud 812 thereon engages and closes switch 813. Such closure of switch 813 closes a circuit through a conductor I820 to the terminal I808 and thence through conductor I808 to the windposition to close both the switches m3 and I804,

however, but continues to advance into a position to engage the shoulder I80Ia on the block I80I before coming to rest. Thus, switch I804 is only momentarily closed by the cam I80I, but switch I803 remains closed so long asthe shoulder I80Ia is engaged by the cam I800. Such momentary closure of the switch I804 extends ground through a conductor I8I0 to the winding of the relay I150, which relay is thereupon momentarily energized to open its contact I151 and therebybreak the holding circuit to the starting relay I154, so that the latter relay is thus deenergized. This causes the timing cam shaft I018 to cease rotating at the end of the machine cycle in which the relay I158 is energized, and

the machine then temporarily ceases its automatic operation under control of said timing shaft, while a total-taking operation ensues, as will be described presently.

Prior to the time automatic operation of the machine is interrupted as above described, the timing c'am I085 momentarily closes the switch I1I6 to energize the solenoid 1I1, as aforesaid, and thereupon the auxiliary printing mechanism is operated to print the last item of variable data V' on that part of the web 90IW which is later to be severed as a proof sheet. Such closure of switch I1I6 also extends battery through a conductor I8II and-the closed switch I803-to a conductor I8I2 which leads to the winding of a solenoid I8I3, Figs. 17, 18 and 22, which solenoid thereupon energizes and retracts its plunger, I8I4. A dog I8I5 is pivotally connected to the plunger, I8I4 and this dog is normally yieldably maintained in engagement with the periphery of a cam I8I1 by a spring I8I6, Fig. 19, but upon energization of the solenoid I8I3 and consequent retraction of the plunger I 8I4, the dog I8I5 is temporarily withdrawn from engagement with the cam I8I1 that is fast on cam. shaft I8I9. Shaft I8I9 tends to be constantly driven through the medium of a friction clutch I820, Fig. 18, by a pulley I82I that is connected through a belt to the main drive shaft I8, Fig. 5. Normally, the friction clutch I 82I merely slips, but when the dog I8I5 is no longer in position to engage a notch I8I8 in the cam I8I1, the shaft I8I9 is free to be driven by the belt pulley I82I through th medium of the clutch I820.

In the course of such rotation of the cam shaft I8I8, a cam I822 thereon closes a switch I823 and battery is thereupon extended from a conductor I824 through the switch I823 and conductor I825 to the winding of a solenoid I826, Figs.

ing of the clutch solenoid 1I1. Thereupon the auxiliary printing mechanism is caused to go through acycle of operationindependently of the other units in the printing machine, and in the course of such operation a total is read out from the accumulator and is printed upon the web 80 IW.

It is undesirable that any changeable data A or number N, Fig. 4, shall appear opposite the printed total on the sheet SM, and hence means have been provided for suppressing the printing of such data when a total taking operation is in progress. To this end, the platen P is constructed with two separate impression surfaces as shown in the front view of Fig. 11. The impression member I830 which affords one of these surfaces is rigidly fastened to the plate 586 of the platen P and a rubber block-I83I secured to the under side of the member I830 cooperates with the means that prints the variable data V' upon the web 80IW. Another impression member I 832 is mounted on the platen P and this member carries a rubber block I833 which cooperates with the printing devices D .and the printing wheels of the numbering mechanism (not shown) for printing the number N' upon the web 80I-W. As is shown in Fig. 11, the plate 586 of the platen P is provided on its upper side with openings or sockets as I834 in-which screws I835 are slidably fitted, these screws being yieldably retained in the positions shown in Fig. 11, by springs I836 interposed between the heads of the screws I835 and the bottoms of the sockets I834. The shanks of the screws I835 pass freely through suitable openings in the plate 586 at the bottoms of the sockets I834 and the lower ends of these screws are threaded into a plate I831 secured tothe impression member I832 of the platen P. The member I 832 is normally maintained in its lowermost position for-cooperation with the printing devices D and the numbering mechanism by cams I838 mounted for rocking movement in suitable openings in the plate 586, these cams being normally so positioned that the circular portions of their peripheries engage the upper side of the plate I831 secured to the yieldably mounted member I832.

Each cam I838 is provided with a fiat I838,'and when a total-taking operation is to be ffected, the cams I 838 are rotated by a means to be disclosed presently, so that the flats I839 thereon are positioned to cooperate with the member I 832. This enables the springs I836 acting upon the screws I835 to retract the member I832 upwardly so that the rubber block I833 thereon does not engage the printing device D which is in printing position at that time, nor the numbering mechanism, and hence the printing of the changeable data A' and number N, Fig. 4, is sup-'
